zpool status issues

[KentShades]

Got a issue on one of our freeNAS boxes here.

• CRITICAL: July 7, 2017, 8:32 a.m. - The volume Storage (ZFS) state is DEGRADED: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state.

Doing a zpool status I get the following:

Code:

[root@NAS07] ~# zpool status -x
  pool: Storage
 state: DEGRADED
status: One or more devices could not be opened.  Sufficient replicas exist for
		the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'.

errors: No known data errors

Just a bad drive here?

 

[Rattlebattle79]

Yes. Bad drive or bad connection. No data loss, but fix the problem ASAP.

 

[KentShades]

Any way to know what drive is bad?!?

 

[Rattlebattle79]

Use "glabel status" to find the device name and match it with the serial number under "view disks" in the webui. The serial number is on the disks. Since you don't have the gptid for that disk in zpool status anymore, I guess you'll have to use the elimination method.

First thing would be to check cables and swap in a known good cable.

This is also why you should note down serial numbers and their location in the server during initial install.

@Bidule0hm 's got a script to map the gptid's to serial numbers. See his Display drives identification infos (Device, GPTID, Serial), here: https://forums.freenas.org/index.ph...d-identification-and-backup-the-config.27365/

Thanks @gpsguy and @Bidule0hm . I'm not a programmer or super scripter, but I made a tiny modification to the script to make it more dynamic:
